A college student is taking two courses. The probability she passes the first course is 0.67. The probability she passes the sec

andrezito [222]

Answer:

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We can solve this question treating the probabilities as a Venn set.

I am going to say that:

Event A: She passes the first course.

Event B: She passes the second course.

The probability she passes the first course is 0.67.

This means that $P(A) = 0.67$

The probability she passes the second course is 0.7.

This means that $P(B) = 0.7$

The probability she passes at least one of the courses is 0.79.

This means that $P(A \cup B) = 0.79$

a. What is the probability she passes both courses

This is $P(A \cap B)$ .

We use the following relation:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.67 + 0.7 - 0.79 = 0.58$

0.58 = 58% probability she passes both courses

Two accounts earn simple interest. The balance y (in dollars) of Account A after x years can be modeled by y=10x+500. Account B

guapka [62]

A has a greater principal

Principal of A is $500, the principal of B is $400, so A's principal is greater by $100

Annual interest rate of A:

10/500 x 100

The interest rate of B is higher.

4) B's annual interest rate is 5% and A's annual interest rate is 2%, so B's is higher by 3%.

Hope this helps! Have a great Tuesday!

The sum of two consecutive odd integers is 256. What is the value of the larger integer?

Igoryamba

Answer:

Step-by-step explanation:

Answer:

The greatest of the integers is 129 (C).

Step-by-step explanation:

Let x be the first integer.

x + (x + 2) = 256

2x + 2 = 256

2x = 254

x = 127

127 + 129 = 256
